Hello,
I am using an older version of VPP(18.01) but I checked the code of 19.04
and I couldn't find any change in problematic area.
I sometimes get a crash with "Show PCI" command.
>From the core, it seems to be crashing here :
"format_vlib_pci_vpd (
s=0x2ad325f2cb58 "0000:02:00.0 0 14e4:1657 5.0 GT/s x2 tg3", ' '
<repeats 13 times>, "HP Ethernet 1Gb 4-port 331i Adapter", args=<optimized
out>)"
I checked this function and it seems that a particular pointer variable
(u8* id) always ends up getting an invalid value - "0x3000000000 <Address
0x3000000000 out of bounds>"
Further down in this function, we try to access this pointer and that
sometimes causes the VPP to crash.
Could it be that the "va_arg" call to get this "id" is returning something
invalid?
Can someone please help me with this ?
Attaching the full stack trace as well.
Regards,
Siddarth
